- Abstract: Reservoir computing is a brain inspired approach for information processing,
well suited to analogue implementations. We report a photonic implementation of
a reservoir computer that exploits frequency domain multiplexing to encode
neuron states. The system processes 25 comb lines simultaneously (i.e. 25
neurons), at a rate of 20 MHz. We illustrate performances on two standard
benchmark tasks: channel equalization and time series forecasting. We also
demonstrate that frequency multiplexing allows output weights to be implemented
in the optical domain, through optical attenuation. We discuss the perspectives
for high speed high performance low footprint implementations.
